Abstract:
In the last years, we are progressively forced to replace conventional energy sources with renewable, green sources. This takes a priority place in the education of pupils and students in high schools and faculties in Romania. To create a right mentality among young people from the viewpoint of using renewable energy sources, it need to understand how devices produce green energy. The transformation of chemical energy into electricity is made by devices called fuel cells. Fuel cells have the ability to meet global power requirements, while being efficient and non- polluting. The most important domain that use combustion cells is the automotive industry. Thus, fuel cell technology is a perfect educational topic for teaching the essential concepts of electrochemical devices, while maintaining students up to date of renewable energy technologies. We have created a computerised educational laboratory system, consisting of three types of combustion cells, to demonstrate and compare the ways of transforming chemical energy into electricity. The analyzed fuel cells are H2 / O2, ethanol and magnesium with salt water. The combustion cell system is an easy and agreeable way to learn fundamental physics concepts. Teaching activities based on this system aim to involve students in exploring scientific methods for formulating and verifying hypotheses, designing and conducting experiments. After obtaining data automatically, students undertake to analyze and interpret experimental data and assume the scientific conclusions.
